Yeah, but what percentage of the time was the CPU stuck blocked on the memory bus for the two workloads?

Also, how was it guaranteeing the page writes were atomic?

You are correct that writes are not guaranteed to be atomic. PostgreSQL has a feature to handle torn pages: full_page_writes = on, which is enabled by default. This means you do double write.

For RocksDB I believe torn pages are not a problem as SST files are immutable. But correct me if I am wrong.
